Procedure

Bubble Viscometer Procedure

  • Knowing the approximate viscosity, pick four standard tubes closest in viscosity to your sample
  • Fill the sample tube with liquid, insert a cork, and then using the tube holder 0577, insert the four lettered tubes and the sample tube into the holder
  • Turn over the holder and visually compare what letter best matches the rise time of the bubble in the sample
  • The rise time in seconds of the sealed tubes and samples can also be determined using a basic timer

Please be aware of the following accuracies when performing the test:
Temperature control: 1 °C = 10 % error
Verticality control: 5° slant = 10 % error
Tube I.D. control: 0.1 mm = 2 % error

 

ASTM D 1545 Timer Method

The tube has three amber ring marks at 27, 100 and 108 mm from the bottom. Fill the tube up to the 100 mm line, insert the cork down to the 108 mm line and turn the tube bottom up. Turn the tube around, start the stop watch when the air bubble crosses the 27 mm line and stop when the bubble crosses the 100 mm line.
